COMBINATION-GAGE.

SPECIFICATION forming part of Letters Patent No. 390,789, dated October9, 1888.

Application lled May 18, i888.

T0 all whom, it may concern:

Beit known that I, WILLIAM BRUcE LIT- TLE, of the city, county, andState of New York, have invented a new and useful Improvement inCombination-Gages, of which the following is a full, clear, and exactdescription.

The object of this invention is to provide for wood-workers acombination-gage which can be readily adjusted and used for mortising,for cutting, for marking two or three different widths,or marking one ortwo widths and cutting another width at the same time, or for marking awidth from the shoulder of a rabbeted or otherwise checked piece of woodat will, and which will yet be ofsimple and durable construction.

The invention comprises Various novel and improved features ofconstruction and arrangement, which will be hereinafter described indetail,and distinctly pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming part ofthis specificatiomin which- Figure l is a side view of a combinationgageembodying my invention. Fig. 2 is a front end view ofthe said gage. Fig.3 is a longitudinal sectional view of the same. Fig. 4 is across-sectional view on theline yy, Fig. 3. Fig. 5 is a cross-sectionalview on the liner s, Fig. 1.

The stock A of the combination-gage thus illustrated to show how myinvention may be practiced is tubular and of metal, having its outer endclosed by a plug, B, and on it is mounted to slide an adjustablecylindrical fence, C, which is provided with a set-screw, D, forclamping it to the stock A in the usual manner.

On one side of the metallic tubular stock A, near the outer endthereof', is iXed a projecting marking-point, E, and on the oppositeside of the stock, somewhat nearer the outer end, is fixed acutting-point, F, so that the gage can be used either to mark or to cuta line on a piece of wood at any desired uniform distance from an edgethereof on adjusting the fence C to the desired distance from the pointE or F.

On the outside of the stock A, angularly midway between the points E andF, is also Serial No. 274,261. (No model.)

fixed a mortise-marking point, G, in line with and inside of which isarranged a longitudinally-adjustable mortise-marking point, H, riding inalongitudinal slot, I, in the stock and projecting from a cylindricalnut, J, which is mounted to slide lengthwise within the stock, but isprevented from turning therein by the engagement of the point H with theslot I.

Y The nut J is threaded to work on a correspondingly-threaded internalspindle, K, the outer end of which has a neck, K', fitted to turn in theinner end ofthe hollow stock,and a milled head, KY, projecting outsideof the stock for turning the spindle,and thus adjusting thepoint-carrying nut J.

The spindle-neck K has an annular groove, K3', to receive a set-screw,L, working through a threaded aperture in the side of the stock A, sothat the spindle willbe held from longitudinal movement, while permittedto turn freely for adjusting the movable mortise-point H with respect tothe stationary mortise-point G according to the desired width of themortise, and when such adjustment has been effected the spindle K, andthus the point H, can be readily locked. The fence C can then be adjusted at the desired distance from the two mortise-pointsGand H in theusual manner. i

The stock A is also formed with a longitudinal slot, M, diametricallyopposite the slot I, through and in which slot M projects and rides amarking-point, M', also carried by the nut J and adjustable therewith,as before. Vith this arrangement, after the fence C has been adjusted toa given distance from the marking-point E or the cutting-point F,abovementioned, the point M can be adjusted to a different distance from thefence C without disturbing the latter, so that the gage can be used tomark or cut two different widths at the same time.

The fence C is formed mostly of wood,with a longitudinal tubular guide,N, at one side, in this case of metal, closed at its outer end by ametallic face-plate, 0, secured on the front of the fence, and at itsinner end by a detachable metallic bearing-plate, P,mortised in andattached to the back of the fence, as shown. In the guide N is mountedto slidelengthwise a cylindrical nut, Q, carrying a marking- IOO point,Q, which projects through a longitudinal slot,R, formed on the outsideof the guide, and thus from the cylindrical surface of the fence, andsaid nut Q is threaded to Work on a screw, R,the outer end of which hasacrosseut head, R", mounted ilush in the outside of the bearing-plate Pfor turning the screw by means of a screw-driver, and thus adjusting thepoint Q'. A lixnit-pin,S,is passed through the screw R inside the plateP to hold the screw against longitudinal Inoveinefnt when turned. Thepoint Q can thus be readily adjusted to any desired distance from thefront of the fence C, for use, as usual, in niarkinga line inside oi" achecked piece of wood.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. A cornbinationgage consisting ofastock provided with fixedmarking-points E F G and adjustable marking-points H M. and a fenceadjustable on the stock and provided with an adjustable marking-pointprojecting from the periphery, substantially as described.

2. In a combination gage, the combination of a tubular andlongitudinally-slotted stock provided with marking-points E F G, athreaded spindle workiugin the tubular stock, and a nut on the spindleand provided with marking-points H M', projecting through the slots ofthe said stock, substantially as herein shown and described.

3. In a gage, the combination of a tubular longitudinally -slottedstock, an adjustable fence, a nut Working in the stock and carrying apoint proj ecting through the said slot, a threaded spindle Workingthrough the nut and having an annularly-grooved neck fitted to turn inthe stock, andan outside head and a set-screw working through the sideof the stock into the annulargroove of the neck,substantially asdescribed.

,4. In a gage, the combination of a stock, a fence adjustable thereonand having an internal longitudinally-slotted guide,a nut working insaid guide and carrying a point projecting from the guide and fence, andmeans for adjusting said nut, substantially as described.

5. A gage-fence having alongitudinal tubular guide at one side closed atits inner end by a detachable bearing-plate,a nut fitted to Work in saidguide and carrying a projecting point, and a screw working through thenut and having its head mounted to turn flush in the detachablebearing-plate, substantially as described.
